AbstractDeep vein thrombosis (DVT) and pulmonary embolism (PE) are together known as venous thrombo-embolism (VTE), one of the most common complications after surgery and trauma injury. In the case of critically ill patients, it is also a significant medical and financial burden, associated with high mortality and morbidity. In recent years, much evidence has come to light showing that DVT prophylaxis can effectively reduce DVT, and it has been incorporated into various evidenced-based guidelines (Geerts et al., 2008; Nicolaides et al., 2006). The objectives of this study are to examine, through a comprehensive literature review of published studies, the effectiveness of various means of DVT prophylaxis aimed at reducing DVT, and to develop an evidence-based guideline for the use of DVT prophylaxis in surgical intensive care unit (ICU) settings. Keywords related to DVT prophylaxis were used in conducting the search in electronic bibliographic databases like MEDLlNE, CINAHL, PubMed and the Cochrane Library. A total of 110 articles were identified, and seven studies fulfilled the inclusion criteria of the study. Data from the seven studies have been extracted to form tables of evidence; the qualities of the studies were then rated, and the levels of evidence assigned according to SIGN 50: A guideline developer’s handbook (Network, Harbour & Forsyth, 2011). Three studies attained a higher level of evidence with strong methodological design and demonstrated a statistically significant reduction in the incidence of DVT. The implementation potential of DVT prophylaxis was examined in terms of target setting, target audience, transferability of findings, feasibility and cost-benefit ratio. And it was found that the development of evidence-based guidelines for DVT prophylaxis was feasible, cost-beneficial and transferable in current settings. The findings of the seven reviewed studies have been translated into an evidence-based DVT prophylaxis guideline. The main focuses of the guideline are the choice of prophylaxis used with surgical ICU patients and the strategies for improving adherence and prophylaxis monitoring. Combined pharmacological and mechanical DVT prophylaxis is recommended for ICU patients who are at high risk of DVT. For patients with active bleeding or high risk of bleeding, mechanical prophylaxis like intermittent pneumatic compressor (IPC) or gradual compression stocking (GCS) should be used first, followed by a review for pharmacological prophylaxis when the risk of bleeding has decreased. In addition, routine assessment of thrombosis and bleeding risk for high-risk ICU patients and regular checking of fitting and functioning of the DVT prophylaxis are recommended. An implementation plan consisting of communication, pilot and evaluation plan was developed. A 12-month programme including communication with stakeholders, marketing of the innovation, training of frontline staff, a five-week pilot study and implementation of the guideline followed by evaluation will be carried out. In the evaluation, programme effectiveness was assessed in terms of patient outcome (e.g. incidence of DVT), process outcomes (e.g. level of knowledge related to DVT, compliance with the guideline and level of staff satisfaction) and system outcome (e.g. financial cost reduction).
